I want to start a scan by pressing the scanner's scan button and have the data delivered to a Linux box.

Unfortunately, I can't use the scanner's WLAN interface, so I'm stuck with USB.

Is there any chance to make this work?

Here's a few speculative ways to achieve this. Did you have success with any of these?

• Run a client on Linux that (partially) adheres to the protocol that's implemented in ScanSnap's Windows and macOS clients (unlikely)


• Install a USB-to-Ethernet adapter on the scanner and get the scanner to use it as an ethernet device. I could then scan to FTP.


• Install the official Windows client via Wine.

scanimage supports the ix500 scanner over usb

example:

scanimage -L

device `fujitsu:ScanSnap iX500:59766' is a FUJITSU ScanSnap iX500 scanner

So what's missing it the trigger from the button. I found

https://www.camroncade.com/cloud-scanner-with-raspberry-pi-fujitsu-ix500-2/

mentioning a scannerbuttond package. There is a german description at:

• 
  https://wiki.ubuntuusers.de/scanbuttond/
  and an english one at


• http://virantha.com/2014/03/17/one-touch-scanning-with-fujitsu-scansnap-in-linux/

Both are a bit outdated but give some hints on the general idea.
Here is a description of a trial with an Ubuntu 18.04 LTS virtual machine.
After installing

sudo apt-get install scanbuttond

I connected the scanner by assigning it's USB device to the virtual machine.

scanimage -L

worked as described above.

sudo sane-find-scanner



  # sane-find-scanner will now attempt to detect your scanner. If the

  # result is different from what you expected, first make sure your

  # scanner is powered up and properly connected to your computer.



  # No SCSI scanners found. If you expected something different, make sure that

  # you have loaded a kernel SCSI driver for your SCSI adapter.

looks promising.

sudo scanbd -d7 -f

starts the daemon in foreground with debugging set to a high level.
In my case i had to comment out some scanner drivers in dll.conf to get rid of results from a different scanner that was available on my network.

Due to bug https://bugs.launchpad.net/ubuntu/+source/scanbd/+bug/1747115
I also had to change the users / group settings.

I added the full path to my test script 5 times in scanbd.conf and 4 times in scanner.d/fujitsu.conf:

root@fur:/etc/scanbd# grep scan.sh scanbd.conf 

                script = "/home/wf/bin/scan.sh"

                script = "/home/wf/bin/scan.sh"

                script = "/home/wf/bin/scan.sh"

                script = "/home/wf/bin/scan.sh"

                script = "/home/wf/bin/scan.sh"

root@fur:/etc/scanbd# cd scanner.d/

root@fur:/etc/scanbd/scanner.d# grep scan.sh fujitsu.conf

                script = "/home/wf/bin/scan.sh"

                script = "/home/wf/bin/scan.sh"

                script = "/home/wf/bin/scan.sh"

with the script scan.sh being:

#!/bin/bash

# WF 2018-12-18

echo "scanning"

echo "scan button pressed on ix500" >> /tmp/ix500.log

i then tested with

sudo scanbd -f

in one terminal and

tail -f /tmp/ix500.log

in another.

scanbd: dbus match type='signal',interface='org.freedesktop.Hal.Manager'

scanbd: SANE_CONFIG_DIR not set

scanbd: Not Primary Owner (-1)

scanbd: Name Error (Connection ":1.96" is not allowed to own the service "de.kmux.scanbd.server" due to security policies in the configuration file)

scanbd: trigger action for page-loaded for device fujitsu:ScanSnap iX500:59766 with script /home/wf/bin/scan.sh

scanning

shows on the daemon's foreground output

and

scan button pressed on ix500

from here it seems be all downhill - the environment variables being passed are described in the scanbd.conf file.

e.g. modifying scan.sh to:

#!/bin/bash

# WF 2018-12-18

echo "scanning"

cat << EOF >> /tmp/ix500.log

scan button pressed on ix500

function: $SCANBD_FUNCTION

mode: $SCANBD_FUNCTION_MODE

device: $SCANBD_DEVICE

action: $SCANBD_ACTION

EOF

will create

scan button pressed on ix500

function: 1

mode: Lineart

device: fujitsu:ScanSnap iX500:59766

action: scan

on the press of the scan button :-)
